7^(-3) = 1/7^3 = 1/343
- 7^3 = - (7^3) = -343
As can be seen, the results are very different.
Answer:
A
Step-by-step explanation:
Speed = distance/ time
=10km/ 1hr(60mins)
= 10km/ 1hr
=10km/hr
Constant of proportionality is 4
equation: x/y = 4
explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.
The correct answer is -15 because the absolute value is 15 but there is a negative outside the absolute value lines making it negative :)
